How to Fix EXCEPTION_ACCESS_VIOLATION (0xC0000005) Game Crash in Windows 11 24H2 (2026 Guide)

You launch a fast-paced multiplayer title like The Finals, ARC Raiders, Counter-Strike 2, or Black Myth: Wukong, and without warning, the screen freezes before dumping you straight to desktop with a dialog box stating: Fatal error: [File:Unknown] [Line: ...] EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000000 or NTSTATUS code 0xC0000005. This error is the single most prevalent runtime exception in PC gaming history, and following the Windows 11 24H2 kernel update, reports of this crash have spiked across modern DirectX 12 and Unreal Engine 5 titles.

Anatomy of 0xC0000005: Why Access Violations Occur

In modern 64-bit protected memory architectures, operating systems enforce strict virtual address space boundaries. An access violation triggers under three specific conditions:

• Null Pointer Dereference (Read Violation 0x00000000): The game engine asks the CPU to read asset or shader data from an unallocated or cleared memory address.
• Third-Party Kernel Driver Collision (`inpoutx64.sys`): In Windows 11 24H2, Microsoft introduced hardened kernel memory isolation. Older RGB lighting utilities (Corsair iCUE, OpenRGB, Razer Synapse, or motherboard RGB bloatware) load unauthenticated ring-0 drivers like inpoutx64.sys that inject hooks into the same memory segments game anti-cheats monitor, instantly triggering a kernel fault.
• DDR5 Memory Bus Timing Instability: High-frequency DDR5 memory (6000MHz to 7200MHz) running on aggressive EXPO/XMP profiles can pass light desktop workloads without issue, but generate single-bit parity errors when subjected to heavy AVX-512 instruction bursts during shader compilation.

Method 1: Purge the Legacy `inpoutx64.sys` RGB Driver Conflict

This fix resolved the widespread crashing issue documented across thousands of systems running Windows 11 24H2:

1. Open File Explorer and navigate to C:\Windows\System32\drivers.
2. Search for inpoutx64.sys or inpout32.sys.
3. Check if the file is present. If found, right-click and check its digital signature. These files are legacy parallel-port drivers recycled by older RGB lighting software to communicate with motherboard SMBus chips.
4. Update your peripheral suites (Corsair iCUE to v5.18+, Razer Synapse to v4+, OpenRGB to latest git build). Modern versions have replaced this driver with sanitized WinUSB calls.
5. If third-party RGB software is uninstalled but the driver remains, delete inpoutx64.sys from Safe Mode or rename it to inpoutx64.sys.bak.

Method 2: Configure Windows Exploit Protection (DEP & CFG)

Unreal Engine 5 titles dynamically generate executable shader bytecode in RAM. If Windows Data Execution Prevention flags this buffer as untrusted, an instant 0xC0000005 termination occurs:

1. Press the Windows Key, type Exploit Protection, and open the system settings panel.
2. Switch to the Program settings tab.
3. Click Add program to customize > Choose exact file path.
4. Browse to your crashing game executable (for instance, TheFinals.exe, cs2.exe, or b1-Win64-Shipping.exe).
5. Scroll down to Control Flow Guard (CFG). Check Override system settings and toggle it to OFF.
6. Scroll to Data Execution Prevention (DEP). Ensure it is set to enable, but turn off Mandatory ASLR for that specific executable.
7. Click Apply and restart the game.

Method 3: DDR5 Memory Frequency & Voltage Stabilization

If crashes happen randomly across multiple games after 15 to 45 minutes of gameplay, memory timing instability is the primary suspect:

• Restart your PC and enter BIOS (Del or F2).
• If running DDR5-6000 or higher on AMD AM5, locate CPU VDDIO / SoC Voltage. Ensure SoC voltage does not exceed 1.25V–1.30V.
• Temporarily disable XMP/EXPO or manually downclock memory speed by 200 MHz (e.g., from 6000 MT/s to 5800 MT/s) while keeping primary timings stock.
• Download and run TestMem5 with the Anta777 Extreme profile or Windows Memory Diagnostic to verify zero hardware memory errors.

Method 4: Flush DirectX Shader Cache & Reinstall Visual C++ All-in-One

Corrupted pre-compiled shader cache binaries cause instant crash-to-desktop during map transitions:

1. Open Windows Disk Cleanup by searching cleanmgr in Start.
2. Select your C: drive, check DirectX Shader Cache, and click OK to delete existing compiled caches.
3. Download the verified Visual C++ Redistributable Runtimes All-in-One package (2015–2026 x86/x64).
4. Right-click install_all.bat as Administrator to ensure zero missing dynamic link libraries (msvcp140.dll, vcruntime140.dll).
5. Execute a system integrity repair in an elevated terminal:

   DISM /Online /Cleanup-Image /RestoreHealth
   sfc /scannow
